[Linuxha-users] Big PE's cause grief

Hello again!
	8Gb PE size?? I've never heard of anything like that before! I
typically use 4Mb as my PE size - that works perfectly will with
partitions with any volume group I use (although the largest VG I use is
only 280GB).

	If there is a good reason for a PE size that large please let me know!

Regards,
Simon.
